Latest threat detection statistics from ESET

Bournemouth, UK (3rd August 2007) – ESET announced today that the trojan Ani.Gen is once again the number one threat to computer users according to ESET’s ThreatSense.Net statistical reporting. July marks the fourth consecutive month that Ani.Gen has topped the threat chart. ESET attributes Ani.Gen’s staying power not only to its wide distribution, but also points out that users not updating their operating systems exasperate the problem.

Win32/TrojanDownloader.Ani.Gen, which exploits how Windows handles animated cursor (.ani) files, requires no action on the user’s part to become infected other than to visit or view an affected website or email. Its success lies in its ability to expose even fairly sophisticated users to “drive by” attacks that can compromise their computers.

“Ani.Gen encompasses the detection of a variety of threats that use the .ANI vulnerability to infect users with other malicious software,” explains Randy Abrams, Director of Education, ESET. “One of the contributing factors to its success is that exploit toolkits will attempt a variety of exploits. Malformed files using this exploit can easily be sent via spam from large botnets, and such files can be included with software such as "free smileys", and of course "free cursors". The effectiveness of the exploit, the variety of vectors in which it can be introduced, and poor patching practices are probably all parts of the reason the threat has stayed on top of the charts.”

The threat from malware designed to propagate via portable storage media, highlighted last month, is still strong with rise of Rjump.A and INF/Autorun to second and third position in the threat chart. The wide use of portable storage media such as USB sticks and memory cards makes them a likely target for malware writers.
